What Buyers Say
Nikon NIKKOR 2178 16-85mm
The Nikon 16-85mm VR is widely praised as an excellent all-around zoom for DX cameras, delivering sharp images across the focal range with effective VR. Users note it outperforms kit lenses like the 18-105mm and even rivals the pricier 17-55mm in sharpness, though it is heavy and somewhat slow (f/3.5-5.6). Build quality is solid with a metal barrel, and the 16mm wide end is a key advantage for landscapes. Some caution about vignetting with thick filters and barrel distortion at 16mm, but overall it is considered a worthy investment for enthusiasts.
